In this paper, the authors present empirical results obtained from Java implementation of Elliptic Curve Cryptosystem (ECC) as an asymmetric block cipher algorithm and a set of symmetric block cipher algorithms namely Triple-Data Encryption Standard (T-DES), Advanced Encryption Standard (AES), and Blowfish. Performance evaluation based on CPU execution time is presented under WinXP and Linux. They used in their implementation Java programming language, Java Cryptography Architecture (JCA) and Java Cryptography Extension (JCE). The evaluation of the performance of these algorithms is done for secret key generation and encryption and decryption operations. Results indicated that ECC outperforms the other encryption/decryption algorithms considered in this paper regarding the security strength, speed, and key size of ECC.
